Dear Darrell,

My '87 has died a few times since I've had it.  More recently, when it
is cold, it has died while idling.  Tonight it died while accelerating,
and I coasted to a parking place.  It started immediately and got me
home with a couple of noticeable cut-outs or hesitations.

First thing back I hooked up the your digitool.  The fuel pump light is
flickering and turning off.  However, it always is bright concurrent
with the starter light.  I'm guessing that it is a bad ground wire or
something along those lines, such that when the starter voltage is
active there are paths with less resistance for the FP signal.  It's
just a theory.  Does the fuel pump get a separate signal while the
starter is on?  It always starts with the fuel from starting it but then
dies after the FP light has been out for a five or six seconds.

I should back up and ask you does this light tell me that there is no
voltage going to the pump from the ECU?  If so, does that mean it is
possible I damaged the ECU or it is shorting out or something?  I hope
not.  :'>[

I haven't even looked at the books yet.  It is dark now, so I'll check
the books, the list and sleep on it.

Thanks all,
